Set working pressure
Starting with 0 psi, slowly adjust air regulator to 15 psi.
No leak should occur, check and lower psi if needed.

STEP 7

Open bleeder screws
Connect clear hose to bleed screw and insert open end into suitable container.
A fluid collector bottle can also be used. Open each bleed screw in sequence for
10-15 seconds or until fluid is clean and bubble free.
Using correct wheel sequence is recommended (RR, RL, FR, FL is most common)

Another advantage of using Speedi-Bleed is the ability to perform fast, effective on vehicle bleeding of the master cylinder.

• Hookup Speedi-Bleed tool
• Place rag under master cylinder brake line fittings.
• Crack open brake line fitting for 5-10 seconds. **
• Close fitting and repeat on other brake lines.
** If air is trapped you will hear and see hissing / spitting.

Fast, Easy and No Helper Required

NOTE: The brakes can usually be bled without first bleeding the pre-installed master cylinder, but a firmer pedal typically results if the master cylinder is fully bled before opening the bleeder screws at each wheel.

When using Speedi-Bleed, the fluid level in the master cylinder is always maintained throughout the bleeding process. This is important in all situations, but even more so when bleeding ABS equipped vehicles, in order to prevent air from entering the ABS system via the master cylinder, from the m/cyl reservoir running dry of fluid.

Bleeding ABS Brakes

Most vehicles with ABS brakes can be bled as normal without any additional procedures or tools required. Simply hookup Speedi-Bleed and open the bleeder screws. Job done. Exceptions do exist thought:

A. The optimal method is to use a bi-directional scan tool to cycle the ABS valves in sequence
and run the ABS pump, in order to fully purge the ABS modulator of trapped air.

B. A workaround method can provide satisfactory results, by first bleeding the conventional brake
circuit via the wheels, followed by activating the ABS during a test drive on vacant parking lot or
back road. An attempted wheel lockup is required by slamming hard on the brake pedal. This
will open up the ABS circuits and release trapped air into the conventional or base circuit. The
brake system is then re-bled at the wheels.
The downside with this method, is that time duration that the ABS circuit will be opened will be
much less than with the scan tool method. Repeated applications of "bleed, ABS stop, bleed"
could be needed to obtain desirable results.

NOTE: Caution should be used if attempting this procedure. Only proceed if safe to do so, and be
aware that the brake pedal could suddenly drop when the air is released from the ABS
system into the wheel circuits. Vehicle speed of 6-10 mph minimum is typically required to
activate the ABS system during an anti-lock application

A small inexpensive tool (valve depressor) is needed to hold open the proportioning valve on the ABS
modulator to facilitate pressure bleeding.

3. Integral ABS

ABS systems installed on some mid 1980's to early 1990's Domestic & European cars, plus 1990-2002
Range Rover, that incorporated the master cylinder together with a high pressure ABS pump/valve
assembly, and accumulator(s) into a single integrated unit (often called ABS Actuator). Integral ABS
systems do not just modulate and control line pressure during anti-lock application, but also provide
power braking during regular operation instead of the typical vacuum assist found on most vehicles

Integral ABS can typically be bled by running the ABS pump and using the pressure stored in the ABS
system to bleed the rear wheels, combined with conventional methods to bleed the front wheels.

Proportioning Valves

In order to pressure bleed some 1960's to 1980's brake systems, the proportioning valve will need held open. This is done by either pushing in or pulling out the valve stem.

Speedi-Bleed Usage Tips

First time usage

A dry run is recommended. This involves hooking up tool and setting the working pressure without any brake fluid in bottle, in order to get a feel for tool operation.

Apply brake fluid to adapter o-ring seal (C500, C600)

Rub brake fluid around rubber o-rings. This will aid with sealing and make the C500/C600 adapter fit into filler neck more smoothly.

Tighten wing nuts evenly and firmly (C100, C200, C300)

Higher working pressures can be obtained if care is taken to center the adapter over the master cylinder reservoir, and the wing nuts tightened properly. When the C100 or C300 adapter is removed from the reservoir, you should see an indentation pattern on the adapter rubber gasket. This will indicate the gasket has "bitten" into the filler neck and good seal was formed.

Always start with 0 psi and slowly increase. Stop every 5-6 psi and check for leaks.

Bleeding master cylinder

More complete brake bleeding (firmer brake pedal) can often be accomplished by first bleeding the master cylinder (on vehicle). Hookup Speedi-Bleed tool, then place a rag under m/cyl brake line fittings. Crack open each fitting with wrench for aprox 5-6 seconds or until fluid is clean and bubble free.

IMPORANT: Integral ABS (used on some 1986-1994 Domestic and European vehicles) must be depressurized before opening any m/cyl brake lines, by turning ignition off and pumping brake pedal 30-40 times.

Bleeding wheels

The wheel sequence of furthest to closest (RR, RL, FR, FL) is most commonly used, and will work fine on the majority of vehicles, but whenever possible the manufacturers stated bleed sequence is recommended. Vehicle specific brake bleeding sequence

Removing tool after using

Adjust the pressure regulator down to 0 psi BEFORE removing the tire nozzle from tire. This will minimize any blowback or brake fluid flowing down air hose and into pressure regulator.

Storing pressure bottle

If Speedi-Bleed is used infrequently, remove brake fluid from bottle before storing.

Cleaning pressure regulator

If brake fluid has entered into regulator it can be typically removed with simple
procedure. With no fluid in pressure bottle, connect tire nozzle to tire. Adjust regulator
to 10-15 psi and then back down to 0 psi. Repeat a few times. This should blow any
fluid inside regulator out of the relief hole.
